What a great game!

Gorf is well-known for introducing or popularizing two new features to the video game market. The first and most notable feature is its robotic voice, powered by the Votrax speech synthesis chip. Most games, even today, that feature human and robot speech use digitized voice samples rather than a speech synthesizer. Secondly, Gorf is one of the first games to allow the player to buy additional lives before starting the game. Most games offer a predetermined number of lives (usually three) and allow the player to earn additional lives throughout the game. Gorf, which was usually set to offer two lives per coin, allows the player to insert extra coins to buy up to seven starting lives.

 

Gameplay is broken up into five distinct "missions", each one essentially a minigame in its own right. Successfully completing all five missions will increase the player's rank and loop back to the first mission. The game continues until the player loses all of their lives. The player can advance through the ranks of Space Cadet, Space Captain, Space Colonel, Space General, Space Warrior, and Space Avenger, with a higher difficulty level at each rank. Along the way, a robotic, synthesized voice heckles and threatens the player, often calling the player by their current rank (for example, "Some galactic defender you are, Space Cadet!").
